PUSH HAY-RAKE.

Specification of Letters Patent.

Patented June 3, 1913.

Application filed April 12, 1910. Serial No. 554,922.

To all 107mm it may concern Be it known that 1, JOHN H. ANDERSON, acitizen of the United States, residing at St. Paul, in the county ofRamsey and State of Minnesota, have invented a new and usefulImprovement in Push I-Iay- Rakes, of which the following is aspecification.

My invention relates to improvements in push rakes.

My object in this device is to make the operation of the machine lighterand more convenient for the operator. In machines of this class thetilting of the teeth of the rake is ordinarily accomplished by means ofa lever manipulated by the man driving the team and it frequentlyhappens that the team cannot be conveniently handled while the driverattends to the raising and lowering of the rake as it takes his entirestrength to move the hand operating lever. By the use of my device therake is positively locked in its raised or lowered position and isconsequently adapted to use on uneven ground. The raising of the raketeeth is accomplished by a system of levers connecting to thewhitlletrees by which the horses are attached to the machine, and to theri id frame carrying the rake teeth thus removing the entire load fromthe operating handle.

In the accompanying drawings with which I have illustrated my device andforming part of my specification, Figure 1 is a perspective view of acomplete push rake; Fig. 2 is a perspective view showing the means ofmounting the rake teeth and the attachment of the tilting bars; F ig. 3illustrates the operators seat and the con nection between the tiltingbars and the whitlletrees; Fig. 4 is an enlarged detail of my device;Fig. 5 is a section on the line A-A of Fig. 1 illustrating the lockingdevice with the rake locked in its raised position, and Fig. 6 is a viewof the same section illustrating the locking device in an intermediateor unlocked position; Fig. 7 is a similar section showing the lockingdevice in its locked down position, and Fig. 8 is an enlarged View ofthe parts connecting the whillletrees and the tilting bars.

In these drawings the same numerals are used to indicate identical partsin the different views.

My device is used in connection with a four wheeled push rake having aseries of teeth 2 attached to a shaft 3 which is jour naled upon wheels4t. Frame 5 is attached to shaft 3 and extends above it forming a stopfor the hay as it moves back along the teeth 2, and is rigidly connectedby brace (S to the rear end of the teeth extending back from the shaft3. Journaled on the shaft 3 are reaches 7 forming a framework, suitablybraced, and connected to the tiller wheels 8.

Attached to the top of frame 5, and spaced apart, are two tilting bars 9which con noct with the tilting device A-A and the operating lover. Thetilting device A-A which is employed for tilting the rake up andallowing it to lower into substantially horizontal position, is doublein form, a set of instrumentalities composing each part being arrangedupon the cross frame 18 and the two sets being disposed on oppositesides of the locking mechanism and hand oper ating lever 20. In thefollowing description, similar parts in the two devices will beindicated by similar numerals.

The tilting device which is attached to the whillletree 10 consists of achain 11 connecting to the whillletree and passing around the pulley 12which is pivotally mounted on the cross frame 13. This chain connects toa rod 1 1 which operates a bell crank 16 also pivotally mounted on theframe 13. To the othe arm of the bell crank 16 is attached the rod 17connecting to the tilting bars 9 in such a manner that the action of thehorse pulling upon chain 11. operates the bell crank and pulls back thetilting bars toward the rear of the machine. This longitudinal movementof the tilting bars transmitted to the frame 5 and the rigidly connectedteeth of the rake causes the rake to be rotated about its bearings inwheels at and the ends of the teeth 2 are raised from the ground. W henthe rake is thus raised, it is locked in position and the pull of thewhilllet-ree is communicated to the cross frame 13 and in no wayinterferes with the pull of the horse on the machine. This is also truewhen the rake is locked in its lower position. The locking of thetilting device is accomplished by locking bars 18 which are attached bybolt 19 to the tilting bars 9 at the point where they connect to theoperating lever 20 and connect to foot lever 21 by bolts 22.

Foot lever 21 is mounted on lugs 23 by means of bolt 25 which alsocarries the tripping lever 24. hen the rake is lifted to its raisedposition either by means of the hand operating lever 20 or the titltingdevice described above, the foot lever 21 falls into the position shownin Fig. 5 and foot pressure on the lever forces the bolts 22 forming itsconnection with the locking bars 18 into a position below bolt 25 whichconnects the foot lever to the lugs 23, and thus securely locks thetilting bars against any forward motion which would tend to lower therake. To unlock the rake from this position, it is necessary only topress on the tripping lever 24 as shown in Fig. 5, thereby raising theyoke 26 connected thereto against the locking bars 18 and raising themout of the locking position shown in Fig. 5, the rake can then belowered by its own weight or a light pressure on the operating handle toits lowest position when the locking bars 18 will assume the positionshown in Fig. 6 where foot pressure on the lever 21 forces the bolts 22again into a position lower than bolt 25 and the tilting bars 9 aresecurely locked against any backward motion which would tend to raisethe rake as shown in Fig. 7. To release the rake from this position thetripping lever 2a is again pressed down raising the yoke 26 against thefoot lever 21 as shown in Fig. 7 and lifting the locking bars 18 out ofthe locking position illustrated in Fig. 7. Thus it is seen that thelever 21 is used in locking the rake in both its raised and loweredpositions while the lever 24: is adapted to unlock the rake from boththese positions. Both the foot lever and tripping lever are so locatedas to be convenient to the feet of the operator seated upon the machineand are so proportioned as to be easily manipulated by the operatorwithout interfering with his handling of the team when driving. The handoperating lever 20 is pivotally mounted on plate 27 at 28 which isattached to the cross frame 18 and is adapted to raise and lower therake when the draft animals are not hitched to it.

In accordance with the patent statutes I have described the principlesof operation of my invention together with the apparatus which I nowconsider to represent the best embodiment thereof but I desire to haveit understood that the construction shown is only illustrative and thatthe invention can be carried out by other means and applied to usesother than those above set forth within the scope of the followingclaims.

Having described my invention, wiat I claim as new and desire to protectby Let ters Patent is 1. In a locking device for a push rake, tiltingbars pivotally connected to said rake, a foot lever, locking barspivoted on said tilting bars and connected to said foot lever, saidlever being adapted to carry the attached ends of the bars in itsmovement beyond a line connecting the pivot points of the lever and barsin either the raised or lowered position of said rake, thereby lookingsaid rake against movement out of these positions, a tripping leverpivoted at the same point as said foot lever and adapted to engage saidfoot lever to unlock said rake, and separate means directly connected tosaid tilting bars to raise and lower said rake.
